Description

Curator's Comment: Description was created based on several sources, including https://www.drugs.com/vantas.html

Histrelin is a gonadotropin releasing hormone (GnRH) agonist that acts as a potent inhibitor of gonadotropin when administered as an implant that delivers continuous therapeutic doses. Following an initial stimulatory phase with increased circulating levels of luteinizing hormone (LH) and follicle-stimulating hormone (FSH), leading to a transient increase in concentration of gonadal steroids (testosterone and dihydrotestosterone in males), continuous administration of histrelin acetate results in decreased levels of LH and FSH due to a reversible down-regulation of the GnRH receptors in the pituitary gland and desensitization of the pituitary gonadotropes. As the product Supprelin LA (FDA), histrelin is indicated for the treatment of children with central precocious puberty (CPP). As the product Vantas (FDA), histrelin is indicated for the palliative treatment of advanced prostate cancer.

Sample Use Guides

In Vivo Use Guide

The recommended dose of VANTAS is one implant for 12 months. Each implant contains 50 mg histrelin acetate to deliver 41 mg histrelin. The implant is inserted subcutaneously in the inner aspect of the upper arm and provides continuous release of histrelin (50 mcg/day) for 12 months of hormonal therapy. VANTAS should be removed after 12 months of therapy

Route of Administration: Other

In Vitro Use Guide

Histrelin at concentrations of 10(-7)M and 10(-8) M (a concentration of 10(-7) M was more effective than 10(-8) M), stimulated significantly VP secretion from isolated rat hypothalamo-neurohypophysial explants
